Agathis robusta, commonly known as Dundathu pine, kauri pine, Queensland kauri (pine), Australian kauri (pine) or smooth-barked kauri, is a coniferous tree in the family Araucariaceae. Although some common names use the word 'pine' it is not a true pine , having leaves rather than needles.
Araucaria angustifolia, the Paraná pine, Brazilian pine or candelabra tree (pinheiro-do-paraná, araucária or pinheiro brasileiro), is a critically endangered species in the conifer genus Araucaria. Although the common names in various languages refer to the species as a "pine", it does not belong in the genus Pinus.
Pinus roxburghii is a large tree reaching 30–50 metres (98–164 feet) with a trunk diameter of up to 2 m (6 + 1 ⁄ 2 ft), exceptionally 3 m (10 ft). The bark is red-brown, thick and deeply fissured at the base of the trunk, thinner and flaky in the upper crown.
The Pinaceae (/ p ɪ ˈ n eɪ s iː ˌ iː,-s i ˌ aɪ /), or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, piñons, larches, pines and spruces. The family is included in the order Pinales, formerly known as Coniferales.
The largest tree by three-dimensional volume is a giant sequoia (Sequoiadendron giganteum), with a volume 1486.9 cubic metres. [19] The smallest is the pygmy pine ( Lepidothamnus laxifolius ) of New Zealand, which is seldom taller than 30 cm when mature. [ 20 ]
Pinus aristata is a medium-size tree, commonly reaching 15 meters (49 ft) in height and occasionally as much as 20 m (66 ft) in their natural habitat.In favorable conditions they are straight and upright trees, but they become increasingly stunted, short, and twisted the closer they grow to timberline.

It is a small to medium-sized evergreen tree, reaching 20 m (66 ft) tall. [4] The leaves are strap-shaped, 6–12 cm (2.4–4.7 in) long, and about 1 cm broad, with a central midrib. The cones are borne on a short stem, and have two to four scales, usually only one (sometimes two) fertile, each fertile scale bearing a single apical seed 10–15 mm
A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3] An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living ...
